Question 610270
A car weighing 2,500lb is parked on a hill inclined 15° to the horizontal. Neglecting friction, what magnitude of force parallel to the hill will keep the car from tolling down the hill? What is the force magnitude perpendicular to the hill?
**
let N=perpendicular force
x=parallel force
..
N=2500 cos 15º≈2415 lbs
x=2500 sin 15º≈647 lbs
